LUBRICATOR.

Patented May 27, 1913 Serial No. 707,191.

To all whom, t may concern Be it known that I, JEssE G. VINCENT, a citizen of the United States of America, residing at Detroit, in the county of Vsayne and State of Michigan, have invented certain new and useful Improvements in Lubricators, of which the following .is a specification, reference being had therein to the accompanying drawings.

The inventonrelates to lubricators and has particular reference to the automatic contro-lling means for the lubricant distribution and the association of the same with a pump as hereinafter set forth.

In the drawings: Figure l is a vertical central section. Fig. 2 is an elevation, partly in section. Y

A is a pump, which, as shown, is of the plunger type and is mounted upon the casing B of an engine. The plunger C, which engages the pump barrel, is provided with a head D engaging the cam E on the engine cani-shaft I?, while a spring G yieldably holds the head D in contactwith the cam. The pump barrel is prorided .with inlet and outlet ports, preferably formed respectively by downwardly and upwardly extending,

- portions II and I of the casing B. The

out-let I is provided with a plurality of branch connections and, as shown, there are two branches extendinglaterally upon opposite sides.

.I and K are check valves, preferably balls, respectively controlling the inlet and outlet ports.

To control the distribution of the lubricant to the several braiich conduits through which it is fed, I have devised an automatic valve which is opened by the pressure de-` veloped by the pump and proportions the distribution to the several conduits. This valve preferably comprises a piston L operating in a cylinder M, a spring N operating to press said piston downward against a stop The branch conduits P and Q Y connect with the cylinder M, and, where the piston is in its depressed position, are completely cut olf from communication with-the outlet from the pump barrel. When, however, the pump is in operation the pressure developed thereby will force the piston VL upward against the tension of the spring N, thereby uncovering the ports of the conduits P and Q and permitting the lubried with a' of the piston, forms an upward limit for the ball check valve K.

S is a nipple on the casing B for connecting a conduit T tothe outlet passage of the pump below the valve L, which conduit T leads to a suitable pressure gage for indicating when the pump is in operation.

U is a by-pass between the u per end of the cylinder M and one of the b duits, which provides for the displacement ci the piston as it moves upward.

7'5 ranchI con- The construction as described forms an exceedingly simple means of distributing proportionate amounts of lubricant through a plurality of conduits from .a single pump. Furthermore, as the valve L is opened by the pressure developed by the pump the pressure gage will positively indicate when the device is in operation.

hatl claim as my invention is:

l. The combination with a pump provided with inlet and outlet .connections of a plurality ot' branch connections to the outlet, and a valve for simultaneously controlling said connections, variablv positioned, by the pressure developed by said pump.

2. The combination with a pump having inlet and outlet connection and a plurality of branch connections for said outlet, of a self-closing valve controlling communication between said out-let and the-several branch l connections, said valve being subjected to the pressure developed in the main outlet to open the same.

3. The combination with a pump having inlet and outlet connections and a plurality ot' branch connections for said outlet, of a piston valve for simultaneously controlling communication between said outlet and the several branch connections, one end of said .piston being subjected to the pressure developed in the main outlet and being operated thereby to its open position, and a spring for closing,r said valve.

4. The combination with a pump having inlet and outlet connections of a cylinder connected with said outlet, a plurality of branch connections respectively communieating with portsin said cylinder, a piston movable in said cylinder to simultaneously and proportionately open and close said ports, one end of said piston being subjected to the pressure developed by said pump, and a spring for moving said piston to a position in which said ports are closed.

5. The combination with a casing forming.,r a pump barrel of a plunger pump in said barrel, valve controlled inlet and outlet connections to said barrel, a cylindei1 with which said outlet communicates, a piston valve in said cylinder, a plurality of branch conduits communicating with ports in said cylinder controlled by said valve, and a spring for closing said valve against the pressure -developed by said pump.

`6. The combination With a pump having valve controlled inlet and outlet connection,

of a cylinder with which said outletl communicates beyond the valve therein, a piston valve in said cylinder, a plurality of branch conduits connecting with ports in said cylinder, controlled by said piston valve, a spring for closing said valve against the pressure developed by said pump, and a connection on the said cylinder between said valves for leading to an indicator.

7. The combination oft a casing having transversely evtendinpr pump and valve barrels, a plunger in said pump barrel, a piston valve in said valve barrel, a` check valve between said pump barrel and valve barrel, a plurality of branch conduits connecting with ports in said valve barrel controlled by the piston valve therein, a spring for movingr said piston valve to the closed position, an a common stop for said piston and check valves arranged therebetween.

8. The combination with a pump provided with inlet and outlet connections, ot' a plurality of branch connections for saidoutlet, and means governed by the pressure developed by the pump for correspondingly con trolling the branch connections.

In testimony whereoi:` I atiiX my signature in presence of two witnesses.
